Hi. I wonder whether anyone can give me the long story short with respect to which licences are required when using icon sets in iPhone/iPad applications. The specific case is with respect to enterprise - i.e. small distribution essential private releases (not on the App Store). However I am also interested to know whether there are additional licensing implications if an app also later goes to the App Store and potentially gets more downloads. For example - can a licence later be upgraded in the event of a longer run ?

Please -- I know I should read the terms and conditions - but I have very poor attention and completely glaze over whenever I start reading the long complicated licence conditions (an if this, then this flow chart would be brilliant but none of the sites seem to offer that). I am mostly likely interested in iStock and Shutterstock btw (but am also open to suggestions if anyone wants to recommend any other sites they like which perhaps have easier to understand licences).

Also - if anyone knows a site which offers RF icon sets in PNG format then I would be very interested to know about that too.

Thanks Sean. I have asked on the iStock forum. I would prefer to buy there since I can convert balance and since I already have some remaining credits. But I need a definitive answer. Found various threads with contradictory answers both at iStock and at developer forums.

Focusing harder I found it in easy to understand words at here at Shutterstock.

                                           Standard           Enhanced
Copies of software and apps   Up to 250,000   Unlimited

^ presumably in the almost infinitely unlikely event of going over 250,000 it is possible to upgrade ?

Thanks for that. That makes sense.

It's especially nice of you to help explain their terms despite everything

ETA: iStock admin agrees with you btw. Thanks again.
